2. A pilot may use a Company staging jumpseat to position himself
in Memphis for the start of his scheduled trip in accordance with
the following:
a. The period beginning at scheduled showtime of a pilot’s
inbound jumpseat and ending 30 minutes after the scheduled
termination of his first duty period must be less than 13:30.
b. There must be at least 1:30 hours between the scheduled
block-in of the inbound jumpseat and the showtime of the
pilot’s trip.
c. A pilot positioning to Memphis on a Company jumpseat
shall take proactive steps to be aware of any circumstance
which could prevent his timely report to work (e.g., potential
maintenance, weather or FAA delays, reroutes). A pilot shall
notify CRS at the fi rst indication that a bump, cancellation,
reroute or delay of his inbound jumpseat may prevent him
from checking in by his scheduled showtime.
d. If a pilot positioning to Memphis on a Company jumpseat
consistent with the provisions of this paragraph cannot report
by showtime due to bump, cancellation, reroute or delay of
his inbound jumpseat, CRS may remove the pilot without
pay. If a pilot is removed under this paragraph, he shall be
eligible for make-up (and shall not be eligible for substitution).
There is no discipline associated with the removal if the pilot
followed the parameters described above.

As said above, just need to be assigned the trip before you stage, if you are still on Reserve when staging in the terms of NHNF do not apply.
